Strain hardening analysis and modelling of its parameters for sintered Al and Al-1%C preforms during cold upsetting

An attempt has been made to model strain hardening parameters for sintered aluminium and aluminium-1%carbon preforms that are subjected to cold upsetting. In addition to compositions, the sintering temperatures and lubricants are considered as variables. The 2k factorial design has been considered t...
